and race their BMW 135i in the 2011 Eurotuner GP and the 2011 Super Lap Battle finals. Rydquist won the Eurotuner GP roadcourse shootout and he also won the most competitive class of the Super Lap Battle, in the process setting a new class track record. In 2012 Rydquist and Berk Technology followed up on their success with a first-time-in-history double win and two new class records in Global Time Attack Limited and Street classes on the same day with the same competition vehicle by simply swapping tires on the Berk Technology BMW 135i. In 2015, following two years of professional drifting in the USA (below), Rydquist returned to sports car racing with German Mercedes-Benz dealer team Motorsport Sing, piloting their SLK 350R in the VLN series at the Nurburgring. A new collaboration with Utah-based CA Sport (Competition Associates) saw his place 5th in class in the 2015 25 Hours of Thunderhill in the team's Nissan 370Z Nismo. The 25-hour endurance race sparked new opportunities with the CA Sport racing team and Rydquist went on to race the team's #34 Nissan 370Z Nismo Touring Car in the season opener of the 2016 Pirelli World Challenge at Circuit of the Americas. Rydquist captured 3rd in the first race and claimed the fastest lap awarding him the pole position for race two. Although the second race seemed to offer the possibility of another podium finish for Rydquist the #34 car had to be retired at the halfway mark due to an unexpected oil leak. In addition to the Pirelli World Challenge Touring Car sprint race at Circuit of the Americas, Rydquist joined California-based Prototype Development Group for a full season campaign with their Factory Five Racing GTM in the 2016 National Auto Sport Association Endurance Racing Championship which the team had won three years in a row. At the first race Rydquist qualified on pole position and won overall. It was a 3 hour long race in mixed weather conditions at Willow Springs International Raceway. He followed up with a flag to flag win from pole position also in the second round at Buttonwillow Raceway. Rydquist drove the 3 hour endurance races solo without a co-driver. Rydquist's championship effort was hampered when the rear axle wheel lugs failed in two consecutive races he was leading big at Willow Spring International Raceway, which dropped Rydquist to 4th and 2nd place finishes respectively.
